Through Ring Rolling, we can optimize issue weight to make it almost equal to the final weight.
Ring Rolling is mainly used for parts with a long interior hole that would mean a considerable loss by other technologies. This way, we can assure great savings by avoiding machining (and losing material) after forging process.
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform with a bigger diametre.
Applications of this process could be ball and roll bearing collars, Steel rims of railway wheels, tube belts, pressure recipients, rotary machines,..
Besides material reduction, Ring Rolling allows shaped walls along with mechanical advantages such as hardening through cold process.
